IMPROVEMENT IN ELECTRO-BATHING APPARATUS.

Specification forming part of Letters Patent No.f22,733, dated January 25, 1859.

y To all whom 'it ma/y concer-n: i

Be it known that I, WILLIAM W. Kanss- NER, of the city of Cincinnati, in the county of Hamilton andState of Ohio, have invented a new and useful Improvement in Electro- Therapeutic Bathing Apparatus; and I do hereby declare the following to b t full and exactdescription thereof, reference being had ters and figures of reference marked thereon, and made to form a part of this specification, like gnres and letters referring to like parts.l

To enable others skilled in the art, to make und use my invention, I will now proceed to describe the same, both as to construction and ffff, the conducting foot-plate h, insulated from the bathtub by the non-conducting suboperation, in doing which I shall refer direct to the accompanying drawings, of which Figure 1 is a top view of the bathing apparatus, and Fig. 2 is a. longitudinal sectional View of the same, exhibiting the position of a patient while taking a bath.

a represents the bath-tub; B, the electromagnetic battery; 0, the positive pole of the battery connected with the bathing-tub; d, the negative pole connecting with the patients feet, insulated from the tub; g, a non-conduct ing substance, insulating; h, the conducting foot-plate from the bathing-tub. This plate is caseitis connected with the negative pole d' of the battery.

ff f f are supportingbands attached to the sides of the bath-tub, and upon which the patient swings in the act of bathing. These bands must be made ot' some non-conducting material, or they m ust be insulated at the edge of the vessel.

The bath-tub is usually made nl' metal, but must always be insulated from the floor by -restin g onT'IIoII-comlnctin g blocks S S, or rglass in their stead.

I do not wish to be understood as broadlyclaiming the insulatinpr ot a patient for the purpose of electro-medical treatment; but

1. The suspending non -conducting bands stance g, all substantially as set forth.

2. The 4 combined use oi' the above-described non-conducting bands f ff f, tho conducting foot-piece h, and the non;onducti|1g substance g, or their equivalents, for the purpose ot' administering an electric bath for therapeutic purposes, as before described.

Signed by the said WILLIAM W. KARSIINER on this 16th day of December, A. D. 1858.
